Unix

Build

Run gradlew build in the project folder

Publish

Run gradle publish in the project folder to generate an SHA256 hash of the zip, and push to S3 for deployment.

Outputs

1. build/deploy -- Folder containing the deployable directory
2. build/project.zip -- AWS deployable zip
3. build/project.sha -- SHA256 hash of the zip for AWS.
4. build/reports/dependency-check -- Folder containing dependency analysis
5. build/reports/coverage -- Folder with test coverage report

PyCharm Setup

PyCharm will not import from Gradle directly, so you need to do a couple of things.

1. Under Settings-> Project Python Interpreter, select the one in the .gradle/python directory
2. Under Settings-> Project Structure, set...
   • /build : excluded
   • /src/main/python : sources
   • /src/test/python : sources
